“Is my debt normal?” is one of those questions people rarely ask out loud. You look at your card balance, your car payment and your mortgage, and you wonder whether everyone else is carrying this much or whether you are quietly in trouble.
The honest tool for that question is your debt to income ratio. It is a simple fraction, lenders lean on it heavily, and it is one of the first things worth looking at in a financial health check. Here is what it measures, what Canada’s mortgage rules actually say, and how to read your own number without panic.
What debt to income actually measures
Take everything you must pay toward debt each month. Divide it by your gross monthly income, which is your pay before tax. The result is a percentage. A ratio of 30% means that out of every $100 you earn, $30 goes straight to debt payments before you buy a single grocery.
Notice what it does not measure. It does not look at your balances, your savings, your rent or what you spend on food. It only asks how big your required payments are next to your income. That makes it a good pressure gauge and a poor full picture, which is why it works best alongside everything else in your financial health score.
GDS and TDS: the two ratios lenders use
When you apply for a mortgage, the lender runs two versions of the fraction. Gross debt service (GDS) counts only housing: mortgage principal and interest, property taxes, heating, and half of any condo fees. Total debt service (TDS) takes that same housing total and adds every other debt you carry, like car loans, credit cards and lines of credit.
| GDS | TDS | |
|---|---|---|
| What it counts | Housing costs only | Housing costs plus all other debts |
| CMHC limit (insured mortgages) | 39% | 44% |
| Divided by | Gross income | Gross income |
Here is a made up example. Say your gross income is $6,000 a month and your housing costs come to $1,800. That is a GDS of 30%. Add a $400 car payment and a $200 card payment and your debts total $2,400, which makes your TDS 40%. Both sit under the CMHC limits, so on paper this household qualifies.
Two quirks worth knowing: the lender tests you at a higher interest rate than you will actually pay (the greater of your contract rate plus 2%, or 5.25%), and it counts credit cards at no less than 3% of the balance a month, even if your real minimum is lower. Both are designed to leave a cushion.
Is your debt normal? The household picture
For context, Statistics Canada tracks the whole country. In the second quarter of 2026, Canadian households owed about 176 cents of credit market debt for every dollar of disposable income, and their principal and interest payments took 14.52% of that income.
Those are national averages across every household, including people with no debt at all and people with big mortgages, and they use after tax income. They are not a score you pass or fail. But they do answer the worried question: carrying debt is normal in Canada. What matters more is how heavy your payments are next to your income, and whether that weight is going up or down.
A lender’s limit is not a comfort level
This is the part most articles skip. A 44% TDS means a lender will let you commit nearly half your gross income to debt. Your real budget runs on take home pay, after tax and deductions, so that same share can feel much tighter once you also pay for food, transport and the rest of life.
There is no official line for “comfortable,” so treat the ratio as a direction rather than a verdict. If it is falling, you are gaining room. If it is rising, because a new loan or a growing card balance is eating more of each paycheque, that is the moment to look closer. And if you are planning a home purchase, our guide to being financially ready to buy a home covers the other pieces lenders weigh.
How to bring your ratio down
There are only two levers: the top of the fraction (your debt payments) and the bottom (your income). Income is slow to change, so the debt side is where most people can act.
The most effective move is usually to remove a whole payment, not shave a little off several. Clearing a car loan or a card balance takes its entire monthly payment out of the ratio at once. If you are not sure which debt to attack first, the debt payoff calculator shows how long each approach takes and what the interest really costs you.
Check your financial health beyond one ratio
Debt to income is one useful number, but it is a snapshot of one corner of your money. A real financial checkup also asks whether your debt is easing or piling on, whether you have a safety net behind it, and where the rest of your paycheque goes.

It shows how heavy your debt payments are, what is driving them, and what to do next, in plain language and without the judgment.
Frequently asked questions
What is a good debt to income ratio in Canada?
There is no single official “good” number for everyday life. For a mortgage, CMHC caps insured borrowers at 39% for housing costs (GDS) and 44% for housing plus all other debts (TDS), measured on gross income. Those are ceilings for borrowing, not targets. The lower your debt payments sit against your income, the more room you have for savings and surprises.
How do you calculate your debt to income ratio?
Add up your monthly debt payments, then divide by your gross monthly income, which is your pay before tax. For a mortgage application, lenders use two versions: GDS counts only housing costs, and TDS adds your other debts such as car loans, credit cards and lines of credit. Rent and everyday costs like groceries are not part of the ratio.
Does debt to income ratio use gross or net income?
Lenders use gross income, your pay before tax. That makes the ratio look smaller than it feels, because your real take home pay is lower. It is worth knowing both: the lender’s number tells you what you can borrow, and your take home number tells you what you can comfortably pay.
Do credit cards count in debt to income ratio?
Yes. For insured mortgages, CMHC counts credit cards and unsecured lines of credit at a payment of no less than 3% of the balance each month, even if your actual minimum is lower. That means a card balance can reduce what a lender will let you borrow.
How can I lower my debt to income ratio?
Two levers: pay down the debts with the highest monthly payments, or raise your income. Clearing a car loan or a card balance often does more for the ratio than a small extra mortgage payment, because it removes a whole monthly payment from the top of the fraction. A debt payoff calculator can show which payment to clear first.
